IFLUID-PRESSURE REGULATOR.

n Specification of Letters Patent.

Patented May 20, 1913.

Application filed January 14, 1913. Serial No. 741,925.

To all whom'z't may concern p Be it known that I, ROBERT N. BAYLIs, a citizen of the United States, residing at East Orange, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Fluid-Pressure Regulators, of which the following is a full, clear, and exact description.

My invention relates to an improved fluid pressure regulator.

In the accompanying drawings, Figure l is a relatively enlarged detail yiew, partly in section. Fig. 3 is a detail view.

1-2 represents the supply and distributing ends of a service pipe, through which gas flows in the direction of the arrows.

These pipes 1 and 2 are coupled by an auto-- matic regulating means to which my 1nven-- tion relates." This regulating means comprises a head 3 having therein a partition 4, through which there is a gas passage 5.

This passage is provided with a valve 6. The valve 6 is a hardened and polished steel ball which is accurately fitted to a seat in the gas passage 5, so that it may properly close the latter when required. This ball valve 6 is carried by theshort end of a lever 7, which is pivoted at 8 close to the valve 6. The other end of this lever is tends laterally from the head 3. In this particular instance the connection between the lever 7 and the diaphragm 9 is a stem or link 11. The diaphragm may be secured to the otherwise open end of the housing 10 in any suitable manner, but preferably by means of a cover 12, which is suitably shaped to correspond with that end of the housing 10 closed by the diaphragm 8. By

the use of clamping screws 13-13 the dia-,

: phragm 9 may be securely clamped between is in its closed position, the

of different sizes may be substituted or added as the occasion requires.

The preferable means for mountin the valve 6 is best seen in the detail viewsfliigs. 2 and 3, in which it will be seen the valve is supported by light spring fingers 1 717, which extend partially under the ball so as to support it close to the vunderside of a hardened presserhead 18 on an adjusting screw 19, which latter is threaded in the short end-of the lever 7. When the valve 6 presser head Wlll he substantially parallel With the plane of the valve seat so that the point of contact on the ball holding it to its seat, will be sub-- stantlally 1n the line of the axis of said valve seat, withthe result that" the pressure of said headjagainst said ball valve will cause said valve to press uniformly entirely around the seat.

. 20 is a, check nut for locking the adjust- 111g screwl9 in a fixed ment".

The valve supporting fingers 17 are preferably formed by first forming a blank havlng radial arms, such as shdwn in Fig. 3,

position after adjustwith a central perforation which slides over i the screw 19, but of less diameter than the head 18, so that said blank will rest upon the head 18. Thesev fingers 1 7 being yield ing, permit the ball 6 to move laterally on the head 18 to such an extent as to properly seat in the gas passage 5 to close the same when desired. By making these fingers 17 of yielding material, accuracy of lateral posltioning of the valve -1s unnecessary, s1'nce the ball can seekAts own correct position y when the presser head 18 is moved so as to vforce the ball against its seat t o close the passage 5; the approximate positioning of said ball being attainedby the use of the yielding supporting means. I

The operation of the device w1ll be readlly understood. The moment an increased volume of gas is demanded, the tendency Wlll be to exhaust the chamber 10 slightly, whereupon the diaphragm 9 will descend,

the lever 7 moving in a direction to open the valve -6 just enough, when the diaphragm 1 is ro erl --wei hted, to supply the needed additi n. If th re is a substantialdecrease in gas being used, the diaphragm will rise and closedown the passage 5 to the proper extent.-

The pressure on the valve 6 bemgln a too line with the axis of the valve seat, is bound I chanical appliance for exerting power, it is obvious that in a broad sense the valve construction and its immediately associated parts may be employed in other connections and operated by other means so long as it embodies the characteristic features heretofore described.

While'the preferred form of valve support is illustrated and described herein as":

embodying light spring fingers, it is obvious that other specific means may be employed so long as such means serves to so support the ball valve thatit is capable of more or less lateral positioning underneath the presser head so that it can seek a center with relation to the valve seat, whereby its pressure against the valve seat Will be uniform entirely around the latter which, broadly speaking, is the function of the particular form of ball support described herein.

What I claim is:

1. In afluid pressure regulator, a head having a fluid passage therethrough, a ball valvefor said assage arranged to seat at the edge of sai passage, a diaphragm controlled means, a presser head for said ball,

said presser head being carried by said dia-' phragm controlled means and being arranged to' engage the ball' on the opposite side from its seat, said ball beinglaterally movable on said head, and a ball centering means arranged to hold the same in substantially the proper position relatively to its seat.

, 2. In a fluid pressure regulator, a head having a fluid passage therethrough, a ball valve for said passage arranged to seat at the edge of saidpassage,a diaphragm controlled lever, a pivotal mounting therefor, an adjustable carrier for said ball, said carrier being mounted at one end of said lever and including a presser head for engaging the ball on the opposite side from its seat, upon which-head said ball is laterally movable, and means coacting with said ball to hold it in substantially the proper position betweensaid presser head and said seat, said means permitting said ball to move laterally sufficiently to find its seat.
